Enum MetadataTypecode 

pub enum MetadataTypecode {
    ExpiryHeight,
    ExpiryTime,
    Unknown(u32),
}

Typecodes for metadata items (0xC0..=0xFC).

Variants

ExpiryHeight

Expiry height (typecode 0xE0). 4-byte little-endian block height.

ExpiryTime

Expiry time (typecode 0xE1). 8-byte little-endian Unix timestamp.

Unknown(u32)

An unknown metadata typecode.

Implementations

impl MetadataTypecode

pub fn is_must_understand(&self) -> bool

Returns whether ZIP 316 requires a reader to understand a metadata item of this type. A reader that does not understand such an item must reject the container that holds it, so the item cannot be dropped without changing the meaning of the container.
